Nickel (atomic symbol: Ni, atomic number: 28) is a Block D, Group 4, Period 4 element with an atomic weight of 58.6934. The number of electrons in each of nickel's shells is 2, 8, 16, 2 and its electron configuration is Ar3d 8 4s 2. Nickel was first discovered by Alex Constedt in 1751.

Dimethylglyoxime is a chemical compound described by the formula CH3C(NOH)C(NOH)CH3. Its abbreviation is dmgH2 for neutral form, and dmgH for anionic form, where H stands for hydrogen. This colourless solid is the dioxime derivative of the diketone butane-2,3-dione (also known as diacetyl). DmgH2 is used in the analysis of palladium or nickel. Its coordination complexes are of theoretical interest as models for enzymes and as catalysts. Many related ligands can be prepared from other diketones, e.g. benzil.
Ni 2+ (aq) + S 2-(aq) NiS(s) Nickel(II) sulfide is not precipitated by adding H 2 S in an acidic solution. In spite of this, NiS is only slightly soluble in HCl and has to be dissolved in hot nitric acid or aqua regia, because NiS changes to a different crystalline form with different properties. Starting with the mass of Ni(DMG) 2 (that is the red precipitate), show the calculation to obtain the moles of Ni 2+ that is present in your Ni-en complex you analyzed. Be sure to include any appropriate chemical reactions that were used in the calculation. Ni 2+ + 2DMG – Ni(DMG) 2.

Dimethylglyoxime can be prepared from butanone first by reaction with ethyl nitrite to give biacetyl monoxime. The second oxime is installed using sodium hydroxylamine monosulfonate:[1]

Complexes[edit]
Dimethylglyoxime is used to detect and quantify nickel, which forms the bright red complex nickel bis(dimethylglyoximate) (Ni(dmgH)2). The reaction was discovered by L. A. Chugaev in 1905.[2]
Cobalt complexes have also received much attention. In chloro(pyridine)cobaloxime[3] the macrocycle [dmgH]22− mimics the macrocyclic ligand found in vitamin B12.
